LG 34WK95U-W 5k resolution with iMac 27" 2019 Radeon Pro Vega 48

New iMac 27" retina 2019 with core I9, radeon pro Vega graphics and an LG 34WK95U, OS X 10.15.3 - I can't achieve the rated resolution of the monitor. Monitor default resolution shows as 3440 x 1440. I see lots of folks with similar issues with MacBook Pro and Catalina. Anyone see this with the iMac? Any resolution to this issue? (pun unfortunate but intended)

thanks

replying to both above - I looked at all the res's available under option>scaled, max was 3820 x 1440, I think, I say think because now its showing me all res, including 5120 x 2160! I installed the LG onscreen control app, worked after a reboot. Don't know if the app updated firmware or drivers, but working now. Hopefully it will hold. Thanks for the replies
